A wand consists of a thin, straight, hand-held stick of wood, ivory, or metal. Generally, in modern language, wands are ceremonial and/or have associations with magic but there have been other uses, all stemming from the original meaning as a synonym of rod and virge, both of which had a similar development.
The Great Book of Saint Cyprian (aka Ciprianillo) gives step-by-step instructions on how to make a magic wand.
The wand is also a pre-Norman unit of length used in the British Isles equal to approximately the modern metre, apparently dating from an early use as a yardstick (originally as a generic term). The 'wand' survived for a time under the Normans. Then when the yard was established, the wand came to be known as the 'yard and the hand', and then disappeared, either slowly or by being banned by law.
The old English unit of 1007 millimetres was called a 'wand', and although the 'yard' was created to replace the wand, the wand was still used for some centuries because of its convenience as part of an old English decimal system that included:
The wand that has survived today as part of folklore may in fact be a rendition of the ancient British length unit. Thus a true wand would be a metre in length and not 30 cm.
In Pharaonic Egypt, toilette articles, weapons against possible enemies, amulets against serpents, were also left in the tomb, together with magic texts and a magic wand which enabled the ka (soul) to use them. The rod of Moses was a hazel wand (Genesis 30:37) as depicted in catacomb frescoes of the third and fourth centuries. In classical Greco-Roman mythology, the god Hermes/Mercury has a special wand called a caduceus.
Six to eight foot long staves with metal tips adorning them are carried traditionally in Freemasonry during rituals of the Craft. Ceremonial uses may have several wands for different purposes, such as the Fire Wand and the Lotus Wand in the Hermetic Order of the Golden Dawn. In Zoroastrianism, there is a similar ritual implement called a barsom. In Wicca and Ceremonial magic, practitioners use several magical tools including wands for the channeling of energy—they serve a similar purpose to the athame although the two have their distinct uses. While an athame is generally used to command, a wand is seen as more gentle and is used to invite or encourage. Though traditionally made of wood, they can also consist of metal or crystal. Practitioners usually prune a branch from an Oak, Hazel, or other tree, or may even buy wood from a hardware store, and then carve it and add decorations to personalize it; however, one can also purchase ready-made wands. In Wicca the wand usually represents the element fire, or sometimes air, although contemporary wand makers also create wands for the elements of earth and water as well. The wand is most often used by modern Pagans, witches, Shamans and others in rituals, healing and spell casting.
There is some scholarly opinion that the magic wand may have its roots in the drumstick of a shaman, especially in Central Asia and Siberia, as when using it to bang on his drum or point, to perform religious, healing, and magical ceremonies.
Magic wands commonly feature in works of fantasy fiction as spell-casting tools. Few other common denominators exist, so the capabilities of wands vary wildly. Note that wands fill basically the same role as wizards' staffs, though staffs generally convey a more 'serious' image; a fairy godmother would definitely use a wand, possibly with a star on the end, while Gandalf would most often not (however, in The Hobbit, he is seen using a wand to fight the goblins of the Misty Mountains and their Wargs). In dramatic fiction, wands can serve as weapons in magical duels. Wands are also common in the fictional fantasy world of J. K. Rowling's Harry Potter series.
The first magical wand featured in the Odyssey: that of Circe, who used it to transform Odysseus's men into animals. Italian fairy tales put them into the hands of the powerful fairies by the late Middle Ages. In the ballads such as Allison Gross and The Laily Worm and the Machrel of the Sea, the villainesses use silver wands to transform their victims. In The Chronicles of Narnia: The Lion, the Witch and the Wardrobe, the White Witch's most feared tool is her wand, whose magic (not necessarily by touch, as in the film) is capable of turning people into stone.
